Hi,

I just purchased a casio FX-9750G and I can't get it to turn on. I followed the "Before using the calculator for the first time instructions" and also tried to use the "P" button on the back, without success.

I tested the batteries that came with the calculator with other devices and they worked fine.

Is there anything else I can do?

Thanks in advance for your help.

I had the same problem too. I just bought it and I was trying to turn it on but it wouldn't though the manual said that it was supposed to automatically when the tab was pulled out. Good news: the Reset button on the back works. I pushed it for some time with the end of a toothpick and it worked.

hope it helps.

If you have pulled out the tab and it wont turn on, get a pin and push the reset button on the back the screen should say Memory cleared or something.

Well when u 1st bought it, you pulled the tab in the back right away i had the same problem w/ 3 of those calculators and i kept returning them. so my suggestion is if u could still return them and get the same 1 but this time read wat the tab says to do

If you want to manipulate 6x6 matrices, you can use one of the CASIO Graphing calculators, such as theCFX-9850GPlus, or the FX-9750G plus.

Graphing calculators from other manufacturers can also handle such matrices. The FX-115ES can handle matrices with dimensions up to 3x3.

There is no button but a menu tab.

In Run screen, enter the number whose factorial you want to calculate ( number can be at most equal to 69), press [OPTN][F6] to get to next page of menus.

No, it does not. You will need a graphing calculator such as the Casio FX-9750G Plus or the newer version FX-9750 GII.

A simple procedure THAT MAY REVIVE the calculator is to reset the calculator by pressing the RESET button on the back. Use a straightened paper clip to press the recessed button.

Hello,

If by calculus problem you mean derivatives of functions, integrals, extrema and such things, I am sorry to inform you that neither the Casio FX-300MS, nor the FX-991MS can handle them. The newer Casio calculator FX-991ES is capable of performing numerical differentiations and integrations. There also graphing calculators by Casio FX-9750G, FX-9860G as well as by Texas Instruments (TI 83 PLUS/TI84PLUS) that are reasonably performant in that area.

Hope it helps.

Sorry to be the carrier of bad news. The calculator FX-7400 G cannot perform matrix calculatioms. Use a Fx-9750G or other calculators.

Hello,

Turn calculator ON. You should see several icons. Use the arrows to highlight the RUN icon. Press [EXE], the screen clears and you are left with a blinking cursor. Now you are ready to start using the basic functions (add, subtract, multiply, etc.). But if you want to do more and pay tribute to the huge capabilities of your calculator, you should take a look at the manual.

Here is the link to all chapters..

I'm having the same problem. It's a huge pain for me to return it (way out of the city and I don't have a car) and I need it for school. Can anyone help?

Thanks!

My calculator works fine, I've had it for 2 years now. Today I went to use it, and it stopped working. I put in brand new batteries, the same type I used before, and it still won't turn on. I need it!

Same deal here. New batteries, but no life. Brand new calc.

I have the same problem.
